The chances of getting all leukemia vary depending on the type of leukemia. Acute myeloid leukemia (AML) is the most common type with an estimated 1 in 4,000 people developing it during their lifetime. Chronic lymphocytic leukemia (CLL), the second most common type, has an estimated 1 in 15,000 incidence rate. The least common type of leukemia, acute promyelocytic leukemia (APL), has an incidence rate of 1 in 100,000.
In general, the risk factors for developing leukemia include age (it is more common in people over the age of 55), gender (males are more likely to develop it than females), family history of leukemia, radiation exposure, and certain viruses. People with certain genetic disorders, such as Down syndrome, are also at greater risk. While the exact cause of leukemia is not known, research suggests that certain environmental factors, such as exposure to certain chemicals or radiation, may increase the risk of developing this cancer.
Unfortunately, there is no way to know for certain if someone will develop leukemia. However, it is important to be aware of the risk factors and to take steps to reduce your risk, such as avoiding exposure to radiation and avoiding contact with certain chemicals. It is also important to discuss any family history of leukemia with your doctor and to talk about any other cancer risk factors that may be present.
